We have a couple:
Earl of Sandwich- Seriously, for under $20 we can get two great sandwiches, two cups of their awesome tomato soup and drinks. We'll eat here two or three times a trip, especially if we can't decide on a TS to go to. Easily the best deal in the World and don't forget the AAA discount!
Ohana- it's a tradition we always try and start our trip with and always gives us that ''We're finally here!'' feeling. Plus we've always had very good food and service when we've gone.
Raglan Road- I go for the beer, DW for the accents. And when everyone talks about their favorite Disney food there's always one I never see mentioned: RR's Guinness Bread with the dipping oil! I could honestly just eat that for my entire meal, especially since it's complimentary, lol.
